The title "Cadillacs and Dinosaurs" and the likenesses of classic Cadillac automobiles were used with the consent of General Motors, who holds the phrase "Cadillacs and Dinosaurs" as a trademark and has licensed it for the comic, the videogame and the animated series.[3]

The original series has been collected multiple times. In 2003, Dark Horse Comics published Xeonozoic Tales Volume 1 on April 23,[4] followed by Volume 2 on July 16,[4] which collected all the stories by Mark Schultz. In November 2010, most of the series, apart from the stories drawn by Steve Stiles, was reprinted in one volume under the title Xenozoic by Flesk Publications. Flesk also released a limited edition hardcover of the book in 2013 after raising funds through Kickstarter.[5] An Artists Edition from IDW Publishing was released in August 2013 and contains oversized reprints of the original art from issues 9 - 14 of the series.[6]

In the storyline, the Earth has been ravaged by pollution and natural disasters of all sorts. To escape this, humanity built vast underground cities in which they lived for approximately 600 years. Upon emerging, the humans found that the world had been reclaimed by previously extinct lifeforms (most spectacularly, dinosaurs).[7] In the new 'Xenozoic' era, technology is extremely limited and those with mechanical skills command a great deal of respect and influence.

The two chief protagonists of the series are mechanic Jack Tenrec and scientist and love interest, Hannah Dundee. Tenrec operates a garage in which he restores cars, particularly Cadillacs. Given that the post-apocalyptic world no longer possesses the ability to refine oil, Tenrec modifies his cars to run on dinosaur guano. These cars, of course, are frequently chased by rampaging dinosaurs in pulp style action-adventure stories.

Other characters include various criminals, politicians, scientists, and inventors who populate the dystopian world of tomorrow. There is also a race of reptilian humanoids who cannot speak in a human language but instead communicate by spelling words with Scrabble tiles. These creatures have befriended Tenrec, and apparently have the ability to communicate telepathically with the dinosaurs. Added into the mix is Hermes, an allosaurus Jack raised, and who basically acts as the most threatening guard dog one could ask for.
